The construction industry faces increasing pressure to minimize environmental impact while improving efficiency and resource management. This paper explores the strategic integration of Circular Economy (CE) principles and Lean Thinking (LT) tools to support the transition towards sustainable construction practices. Although both concepts have independently shown benefits, CE in reducing material waste and promoting resource loops, and Lean in enhancing operational efficiency, few studies address their combined impact within the built environment. Through a literature-based analysis, the paper identifies five shared core principles: waste reduction, value creation, resource optimization, circularity, and systems thinking. It further proposes how Lean tools, such as Value Stream Mapping and Just-In-Time delivery, can practically support CE strategies like reuse, recycling, and lifecycle extension in construction projects. This integrated approach offers a framework tailored for the construction industry to align with the goals of Bahrain Vision 2030, which emphasizes sustainable development, private sector-led growth, and efficient resource utilization. The paper presents a conceptual model for combining Circular Economy and Lean Thinking practices to foster environmental responsibility, improve project efficiency, and create long-term value in the built environment. It concludes by discussing implementation advantages and identifying opportunities for future research at both operational and policy levels. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2026.
